Exploring Second Grade Envision Math Concepts

The video tutorial introduces the concept of force and explores fractions using circles. It begins by discussing how a circle can be divided into fourths, explaining that nine fourths make two whole circles with one fourth left over. The tutorial then explores how circles can be divided into eighths and halves, providing a visual understanding of these fractions. The lesson encourages students to think about the concept of force and fractions throughout the tutorial.
